Reaction Steps

A solution of 38.5 g (0.1 mole) of α,α-bis(4-methylphenyl)-1-(phenylmethyl)-4-piperidinemethanol in 500 ml of absolute ethanol was hydrogenated at 50 psi and 60° C. over 5% palladium on carbon in a Parr apparatus for 3 days. The cooled mixture was filtered through Celite® and the filtrate was concentrated under reduced pressure to give a glass as residue. The glass was crystallized from 2-propanol to yield 17.7 g (60%) of white solid, m.p. 150°-153° C.
